Okay, the structure itself is not a problem, I just thought it is not
really necessary. But to keep things simple I've taken another approach
for v2 of this series: Just use the first SYSMMU of the controllers list
to link the device and the IOMMU. When the owner structure exists there
is always one entry in this list, so that should work fine.
